HOWTO USEYOUR LAWN MOWER
ENGiNESPEED
The engine speed was set at the factory
for optimum performance. Speed is not
adjustable.
ENGINE ZONE CONTROL
_:i_,CAUTION: Federal regulations require
an engine control to be installed on this
lawn mower in order to minimize the
risk of blade contact injury, Do not under
any circumstances attempt to defeat the
function of the operator control. The blade
turns when the engine is running.
o Your lawn mower is equipped with an
operator presence control bar which
requires the operator to be positioned
behind the lawn mower handle to start
and operate the lawn mower.
DRIVE CONTROL
o Self-propelling is controlled by holding
the operator presence control bar down
to the handle and pushing the drive
control lever forward until it clicks; then
releasing the lever.
o Forward motion will stop when the op-
erator presence control bar is released,
To stop forward motion without stopping
engine, release the operator presence
control bar slightly until the drive control
disengages, Hold operator presence
control bar down against handle to con-
tinue mowing without self-propelling.
o To keep drive control engaged when
turning corners, push down on handle
and lift front wheels off ground while
turning lawn mower.
TO ADJUST CUTTmNG HEIGHT
Raise wheels for low cut and lower wheels
for high cut, adjust cutting height to suit
your requirements, Medium position is
best for most lawns.
o To change cutting height, squeeze
adjuster lever toward wheel. Move wheel
up or down to suit your requirements. Be
sure all wheels are in the same setting.
NOTE: Adjuster is properly positioned
when plate tab inserts into hole in lever.
Also, 9-position adjusters (if so equipped)
allow lever to be positioned between the
plate tabs.

ADD OraL
Your lawnmower is shipped without oil in
the engine. For type and grade of oil to
use, see "ENGINE" in the Maintenance
section of this manual.
_1, CAUTmON: DO NOT overfill engine with
oil, or it will smoke heavily from the muffler
on startup.
1. Be sure lawnmower is level.
2. Remove oil dipstick from oil fill spout.
3. You receive a container of oil with the
unit. Slowly pour the entire container
down the oil fill spout into the engine.
NOTE: Initial oil fill requires only 18 oz.
due to residuat oil in engine from the
manufacturers t00% quality testing. When
changing oil you may need 20 oz.
4. Insert and tighten dipstick.
IMPORTANT:
o Check oil level before each use. Add oil
if needed. Fill to full line on dipstick.
o Change the oil after every 25 hours of
operation or each season. You may
need to change the oil more often
under dusty, dirty conditions. See "TO
CHANGE ENGINE OIL:' in the Mainte-
nance section of this manual.
ADD GASOLINE
o Fill fuel tank to bottom of tank filler neck.
Do not overfill. Use fresh, clean, regular
unleaded gasoline with a minimum of
87 octane. Do not mix oil with gasoline.
Purchase fuel in quantities that can be
used within 30 days to assure fuel fresh-
ness.
CAUTION: Wipe off any spilled oil or
fuel. Do not store, spill or use gasoline
near an open flame.
A CAUTION: Alcohol blended fuels
(called gasohol or using ethanol or metha-
nol) can attract moisture which leads to
separation and formation of acids during
storage. Acidic gas can damage the fuel
system of an engine while in storage. To
avoid engine problems, the fuel system
should be emptied before storage of 30
days or longer. Empty the gas tank, start
the engine and let it run until the fuel lines
and carburetor are empty. Use fresh fuel
next season. See Storage Instructions for
additional information. Never use engine
or carburetor cleaner products in the fuel
tank or permanent damage may occur.

TO STOP ENGmNE
o To stop engine, release operator pres-
ence control bar,
TO START ENGINE
NOTE: Due to protective coatings on the
engine, a small amount of smoke may be
present during the initial use of the prod-
uct and should be considered normal.
1. To start a cold engine, push primer
three (3) times before trying to start.
Use a firm push. This step is not
usually necessary when starting an
engine which has already run for a few
minutes.
2. Hold operator presence control bar
down to the handle and pull starter
handle quickly. Do not allow starter
rope to snap back.
NOTE: In cooler weather it may be neces-
sary to repeat priming steps. In warmer
weather over priming may cause flooding
and engine will not start. If you do flood
engine, wait a few minutes before attempt-
ing to start and do not repeat priming
steps.

MULCHINGMOWmNGTiPS
iMPORTANT:Forbestperformance,
keepmowerhousingfreeof built-up
grassandtrash.See"CLEANING"inthe
Maintenancesectionofthis manual.
, The special mulching blade will recut
the grass clippings many times and
reduce them in size so that as they fall
onto the lawn they will disperse into
the grass and not be noticed. Also, the
mulched grass will biodegrade quickly
to provide nutrients for the lawn, Always
mulch with your highest engine (blade)
speed as this will provide the best recut-
ting action of the blades,
o Avoid cutting your lawn when it is wet,
Wet grass tends to form clumps and
interferes with the mulching action. The
best time to mow your lawn is the early
afternoon, At this time the grass has
dried, yet the newly cut area will not be
exposed to direct sunlight.
o For best results, adjust the lawn mower
cutting height so that the lawn mower
cuts off only the top one-thkd of the
grass blades. If the lawn is overgrown it
will be necessary to raise the height of
cut to reduce pushing effort and to keep
from overloading the engine and leaving
clumps of mulched grass, For extremely
heavy grass, reduce your width of cut
by overlapping previously cut path and
mow slowly,
MAX 1/3
o Certain types of grass and grass
conditions may require that an area be
mulched a second time to completely
hide the clippings, When doing a sec-
ond cut, mow across (perpendicular) to
the first cut path,
o Change your cutting pattern from week
to week. Mow north to south one week
then change to east to west the next
week, This will help prevent matting and
graining of the lawn,

GENERAL RECOMMENDATmONS
The warranty on this lawn mower does not
cover items that have been subjected to
operator abuse or negligence. To receive
full value from the warranty, operator must
maintain unit as instructed in this manual.
Some adjustments will need to be made
periodically to properly maintain your unit.
At least once a season, check to see if
you should make any of the adjustments
described in the Service and Adjustments
section of this manual.
o At least once a year, replace the spark
plug, clean or replace air filter element
and check blade for wear. A new spark
plug and clean/new air filter element
assure proper air=fuel mixture and help
your engine run better and last longer.
o Follow the maintenance schedule in this
manual.
BEFORE EACH USE
o Check engine oil level.
o Check for loose fasteners.
LUBRmCATION
Keep unit well lubricated
(See "LUBRICATION CHART"),
LUBRmCATmON CHART

forming any maintenance,
TIRES
o Keep tires free of gasoline, oil, or insect
control chemicals which can harm rubber,
o Avoid stumps, stones, deep ruts, sharp
objects and other hazards that may
cause tire damage,
DRIVE WHEELS
Check front drive wheels each time before
you mow to be sure they move freely.
The wheels not turning freely means
trash, grass cuttings, etc. are in the drive
wheel area and must be cleaned to free
drive wheels.
If necessary to clean the drive wheels, be
sure to clean both front wheels.
1. Remove hubcaps, Iocknuts & washers.
2. Remove wheels from wheel adjusters.
3. Remove any trash or grass cuttings
from inside the dust cover, pinion and/
or drive wheel gear teeth.
4. Put wheels back in place.
NOTE: If after cleaning, the drive wheels
do not turn freely, contact a Sears or other
qualified service center.
BLADE CARE
For best results, mower blade must be
kept sharp. Replace a bent or damaged
blade.
TO REMOVE BLADE
1, Disconnect spark plug wire from spark
plug and place wire where it cannot
come in contact with plug.
2, Turn lawn mower on its side, Make
sure air filter and carburetor are up,
3, Use a w,ood block between blade and
mower housing to prevent blade from
turning when removing blade bolt.
NOTE: Protect your hands with gloves
and/or wrap blade with heavy cloth,
4, Remove blade bolt by turning counter-
clockwise.
5, Remove blade and attaching hardware
(bolt, lock washer & hardened washer),
NOTE: Remove the blade adapter and
check the key inside hub of blade adapter,
The key must be in good condition to work
properly. Replace adapter if damaged,
TO REPLACE BLADE
1, Position the blade adapter on the en-
gine crankshaft, Be sure key in adapter
and crankshaft keyway are aligned,
2. Position blade on the blade adapter
aligning the two (2) holes in the blade
with the raised lugs on the adapter.
3. Be sure the trailing edge of blade (oppo-
site sharp edge) is up toward engine.
4. Install the blade bolt with the lock
washer and hardened washer into
blade adapter and crankshaft.
5. Use block of wood between blade and
lawn mower housing and tighten the
blade bolt, turning clockwise.

TO SHARPEN BLADE
NOTE: We do not recommend sharpening
blade- but ifyou do, be sure blade is balanced.
Care should be taken to keep the blade bal-
anced.An unbalanced blade will cause even-
tual damage to lawn mower or engine.
o The blade can be sharpened with a file
or on a grinding wheel. Do not attempt
to sharpen while on the mower.
o To check blade balance, drive a nail into
a beam or wall. Leave about one inch of
the straight nail exposed. Place center
hole of blade over the head of the nail.
If blade is balanced, it should remain in
a horizontal position. If either end of the
blade moves downward, sharpen the
heavy end until the blade is balanced.
GRASS CATCHER
(if purchased as an accessory)
o The grass catcher may be hosed with
water, but must be dry when used.
o Check your grass catcher often for dam-
age or deterioration. Through normal
use it will wear. If catcher needs replac-
ing, replace only with approved replace-
ment catcher shown in the Repair Parts
section of this manual. Give the lawn
mower model number when ordering,

GEAR CASE
o To keep your drive system working
properly, the gear case and area around
the drive should be kept clean and free
of trash build=up. Clean under the drive
cover twice a season.
o The gear case is filled with lubricant to the
proper level at the factory. The only time
the lubricant needs attention is if service
has been performed on the gear case.
o If lubricant is required, use only Elf Mul=
tis EP00. Do not substitute.

TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
NOTE: Although multi=viscosity oils
(5W30, 10W30 etc.)improve starting in
cold weather, these multi=viscosity oils will
result in increased oil consumption when
used above 32°R Check your engine oil
level more frequently to avoid possible
engine damage from running low on oil.
Change the oil after every 25 hours of opera=
tion orat least once a year if the lawn mower
